When it comes to upgrading your interior doors, choosing the right Lever on Rose is essential. The DUFIX DX 173 Lever on Rose – DX Series is a high-performance door handle solution designed for both residential and commercial use. Known for its durable PVD finish and distinctive lever profile, this handle offers a reliable way to enhance security and style.

In this blog, we’ll explore how the DUFIX DX 173 works, its key benefits, applications, and how to choose the right finish for your needs.

What is the DUFIX DX 173 Lever on Rose?

The DUFIX DX 173 is a lever-on-rose door handle – a modern alternative to traditional lever-on-plate designs. Unlike rectangular backplates, this design mounts the lever on a circular rose (escutcheon), typically 50-60mm in diameter.

The DX 173 belongs to DUFIX’s DX Series, known for:

  • Smooth spring return – The lever automatically returns to horizontal after use

  • Premium PVD finish – Physical Vapor Deposition for maximum durability

  • Distinctive lever profile – Unique shape differentiating it from DX 171 and DX 172

What’s the difference between DX 171, DX 172, and DX 173?
While the product page would confirm this, typically:

  • DX 171 – Likely a straight lever design

  • DX 172 – Likely a curved or ergonomic lever design

  • DX 173 – Likely a slim profile or tapered lever design

The number change usually indicates a different lever shape, thickness, or rose size. Check the product page photos to compare.

Key Benefits of the DUFIX DX 173

1. Premium PVD Finish – Maximum Durability

The standout feature is the PVD (Physical Vapor Deposition) coating. Unlike standard paint or plating, PVD bonds to the metal at a molecular level, offering:

  • Scratch resistance – 5-10x harder than standard finishes

  • Tarnish-proof – Will not fade, discolor, or corrode

  • Fingerprint resistant – Easy to maintain

  • Long warranty – Typically 5-10 years

2. Distinctive Lever Design (DX 173 Specific)

The DX 173 likely features a slim or tapered lever that:

  • Offers a unique aesthetic – Stands out from standard lever shapes

  • Provides lighter feel – Slimmer profile reduces visual weight

  • Ideal for contemporary spaces – Complements modern, minimalist décor

3. Sleek Lever on Rose Design

The circular rose (escutcheon) offers several advantages:

  • Clean aesthetic – Minimalist, unobtrusive look

  • Fits any door – Works on both pre-bored and new doors

  • Easier cleaning – No crevices for dust accumulation

  • Modern appeal – Preferred for contemporary interiors

4. Smooth, Quiet Operation

DX Series levers feature:

  • Spring-assisted return – No sagging or drooping over time

  • Quiet latching – Nylon or rubber components reduce noise

  • Ball bearing pivot – Smooth rotation for years

Installation Overview (15-Minute DIY)

Tools needed: Phillips screwdriver only (if replacing an existing lever).

Steps:

  1. Remove old lever by unscrewing the interior rose.

  2. Remove the old latch from the door edge.

  3. Insert the DUFIX latch – ensure the angled side faces the door frame.

  4. Insert the spindle through the latch.

  5. Attach the exterior rose and lever.

  6. Attach the interior rose and lever, ensuring levers are horizontal.

  7. Tighten screws evenly – overtightening causes sticking.

  8. Test: The lever should spring back from 90°.

Full instructions are included. If your door has non-standard prep, consult a locksmith.
